WATCH: Joe Biden Cries On The 'Today' Show

Biden made a surprise trip to Iraq this week ahead of the U.S.'s
full troop withdrawal and sat down for an interview with
Ann
Curry there.

Biden got quite emotional when discussing his son Beau's service:

All I could think of was those fallen angels whose parents were
in Dover to recover their child. I'm sorry. This -- anyway,
I say to them, be proud of what you did for your country, be
proud of the example you showed the world, and, most of all, be
proud of how you protected your fellow soldiers.

Also of note: Biden is not closing the door on 2016.

I'm never ready to close the door on anything. That is a foolish
thing to do. I learned a long time ago. My dad had an expression.
He said, Joe, remember, never argue with your wife about anything
that is going to happen more than a year from now, and don't make
decisions about anything that is going to happen more than a year
from now. I am intent on re-electing Barack Obama president
of the United States of America. The rest will take care of
itself.
